Chinese authorities in the Henan province announced a total of 302 people had been killed, more than three times the previous toll of 99 reported last week

Another 50 people are still missing.

Most of the fatalities were recorded in the provincial capital Zhengzhou, a city of 12 million that lies along the Yellow River, where 292 lives were lost and 47 people remain missing.

Authorities said a total of 39 people died in underground areas of the city – such as garages and tunnels – including the 14 on subway Line 5.

A total of 189 people were killed by floods and mudslides, while 54 died in house collapses.

The death toll remained at six in an expressway tunnel from which 247 vehicles were removed as it was drained of water.
